About this manual Its purpose The’ purpose of this manual is to help you get the best value from your vehicle. It can do so in several ways. It can help you decide what work must be done, even if you choose to have it done by a dealer service department or a repair shop; it provides information and procedures for routine maintenance and servicing; and it offers diagnostic and repair procedures to follow when trouble

occurs. We hope you use the manual to tackle the work yourself. For many simpler jobs, doing it yourself may be quicker than arranging an appointment to get the vehicle into a shop and making the trips to leave it and pick it up. More importantly, a lot of money can be saved by avoiding the expense the shop

must pass on to you to cover its labor and overhead costs. An added benefit is the sense of satisfaction and accomplishment that you feel after doing the job yourself.

Using the manual The manual is divided into Chapters. Each Chapter is divided into numbered Sections, which are headed in bold type between horizontal lines. Each Section consists of consecutively numbered paragraphs. At the beginning of each numbered Section you will be referred to any illustrations which apply to the procedures in that Section. The reference numbers used in illustration captions pinpoint the pertinent Section and the Step within that Section. That is, illustration 3.2 means the illustration refers to Section 3 and Step (or paragraph) 2 within

that Section. Procedures, once described in the text,

are not normally repeated. When it’s necessary to refer to another Chapter, the reference will be given as Chapter and Section number. Cross references given without use of the word “Chapter” apply to Sections. and/or paragraphs in the same Chapter. For example, “see Section 8” means in the same Chapter. References to the left or right side of the vehicle assume you are sitting in the driver’s seat, facing forward. Even though we have prepared this manual with extreme care, neither the publisher nor the author can accept responsibility for any errors in, or omissions from, the infor-

mation given.

NOTE A Note provides information necessary to properly complete a procedure or information which will make the procedure easier to understand.

CAUTION A Caution provides a special procedure or special steps which must be taken while completing the procedure where the Caution is found. Not heeding a Caution can result in damage to the assembly

being worked on.

WARNING A Warning provides a special procedure or special steps which must be taken while completing the procedure where the Warning is found. Not heeding a Warning can result in personal injury. ?

Introduction to the full-size

Chevrolet and GMC pick-ups The 1988 and later full-size (C and K model) Chevrolet and GMC pick-up trucks have a conventional front engine/rear wheel drive layout. Four-wheel drive (4WD) is available on some models. The V6 and V8 engines equipped in these vehicles use Throttle Body Injection (TBI) on early models (1988 through 1995) or Central Sequential Fuel Injection (Central SFI)

Buying parts Replacement parts are available from many sources, which generally fall into one of two categories - authorized dealer parts departments and independent retail auto parts stores. Our advice concerning these parts is as follows: Retail auto parts stores: Good auto parts stores will stock frequently needed components which wear out relatively fast, such as clutch components, exhaust systems, brake parts, tune-up parts, etc. These

stores often supply new or reconditioned

parts on an exchange basis, which can save a considerable amount of money. Discount auto parts stores are often very good places to buy materials and parts needed for general

unique to the vehicle and not generally available elsewhere (Such as major engine parts, transmission parts, trim pieces, etc.).

still covered under warranty, be sure that any replacement parts purchased - regardless of the source - do not invalidate the warranty! To be sure of obtaining the correct parts, have engine and chassis numbers available and, if possible, take the old parts

such as oil, grease, fil-

ters, spark plugs, belts, touch-up paint, bulbs, etc. They also usually sell tools and general accessories, have convenient hours, charge lower prices and can often be found’ not far from home. Authorized dealer parts department: This is the best source for parts which are

Maintenance techniques, tools and working facilities Maintenance techniques There are a number of techniques involved in maintenance and repair that will be referred to throughout this manual. Application of these techniques will enable the home mechanic to be more efficient, better organized and capable of performing the various tasks properly, which will ensure that the repair job is thorough and complete.

Fasteners Fasteners are nuts, bolts, studs and screws used to hold two or more parts together. There are a few things to keep in mind when working with fasteners. Almost all of them use a locking device of some type, either a lockwasher, locknut, locking tab or thread adhesive. All threaded fasteners should be clean and straight, with undamaged threads and undamaged corners on the

hex head where the wrench fits. Develop the

habit of replacing all damaged nuts and bolts with new ones. Special locknuts with nylon or fiber inserts can only be used once. If they are removed, they lose their locking ability and must be replaced with new ones. Rusted nuts and bolts should be treated with a penetrating fluid to ease removal and prevent breakage. Some mechanics use turpentine in a spout-type oil can, which works quite well. After applying the rust penetrant, let it work for a few minutes before trying to loosen the nut or bolt. Badly rusted fasteners may have to be chiseled or sawed off or removed with a special nut breaker, available at tool stores. lf a bolt or stud breaks off in an assembly, it can be drilled and removed with a special tool commonly available for this purpose. Most automotive machine shops can perform

this task, as well as other repair procedures, such as the repair of threaded holes that

have been stripped out. Flat washers and lockwashers, when removed from an assembly, should always be replaced exactly as removed. Replace any damaged washers with new ones. Never use a lockwasher on any soft metal surface (such as aluminum), thin sheet metal or plastic.

Fastener sizes For a number of reasons, automobile manufacturers are making wider and wider use of metric fasteners. Therefore, it is important to be able to tell the difference between standard (sometimes called U.S. or SAE) and metric hardware, since they cannot be interchanged. All bolts, whether standard or metric, are sized according to diameter, thread pitch and

0-9

Maintenance techniques, tools and working facilities length. For example, a standard 1/2 - 13 x 1 inch and is 1 inch long. An M12 - 1.75 x 25 metric bolt is 12 mm in diameter, has a thread

pitch of 1.75 mm

(the distance

greater the strength of the nut. Metric studs are also marked on their ends according to property class (grade). Larger studs are numbered (the same as metric bolts), while smaller studs carry a geometric code to denote grade. It should be noted that many fasteners, especially Grades 0 through 2, have no distinguishing marks on them. When such is the case, the only way to determine whether it is standard or metric is to measure the thread pitch or compare it to a known fastener of the

dard bolts have slashes radiating out from the center of the head to denote the grade or strength of the bolt, which is an indication of the amount of torque that can be applied to it. The greater the number of slashes, the greater the strength of the bolt. Grades 0 through 5 are commonly used on automobiles. Metric bolts have a property class (grade) number, rather than a slash, molded into their heads to indicate bolt strength. In

bolt is 1/2 inch in diameter, has 13 threads per

between

threads) and is 25 mm long. The two bolts are nearly identical, and easily confused, but they are not interchangeable. In addition to the differences in diameter, thread pitch and length, metric and standard bolts can also be distinguished by examining the bolt heads. To begin with, the distance across the flats on a standard bolt head is measured in inches, while the same dimension on a metric bolt is sized in millimeters (the same is true for nuts). As a result, a standard wrench should not be used on a metric bolt anda metric wrench should not be used on a standard bolt. Also, most stan-

the bolt. Property class numbers 8.8, 9.8 and 10.9 are commonly used on automobiles. Strength markings can also be used to distinguish standard hex nuts from metric hex nuts. Many standard nuts have dots

Since fasteners of the same size (both standard and metric) may have different strength ratings, be sure to reinstall any bolts, studs or nuts removed from your vehicle in their original locations. Also, when replacing a fastener with a new one, make sure that the new one has a strength rating equal to or greater than the original. j

loose.

Bolts, screws

studs, depending on the material they are made of and their thread diameters, have specific torque values, many of which are

noted in the Specifications at the beginning of each Chapter. Be sure to follow the torque

aluminum). As was previously mentioned, the size and grade of a fastener determine the amount of torque that can safely be applied to it. The figures listed here are approximate for Grade 2 and Grade 3 fasteners. Higher grades can tolerate higher torque values. Fasteners laid out in a pattern, such as cylinder head bolts, oil pan bolts, differential cover bolts, etc., must be loosened or tightened in sequence to avoid warping the component. This sequence will normally be shown in the appropriate Chapter. If a specific pattern is not given, the following procedures can be used to prevent warping.

Maintenance techniques, tools and working facilities

Micrometer set

Initially, the bolts assembled finger-tight should be tightened one criss-cross or diagonal

or nuts should be only. Next, they full turn each, in a pattern. After each one has been tightened one full turn, return to the first one and tighten them all one-half

turn, following the same pattern. Finally, tighten each of them one-quarter turn at a time until each fastener has been tightened to the proper torque. To loosen and remove the fasteners, the procedure would be reversed.

Component disassembly Component disassembly should be done with care and purpose to help ensure that the parts go back together properly. Always keep track of the sequence in which parts are removed. Make note of special characteristics or marks on parts that can be installed more than one way, such as a grooved thrust washer on a shaft. It is a good idea to lay the disassembled parts out on a clean surface in the order that they were removed. It may also be helpful to make sketches or take instant photos of components before removal. When removing fasteners from a component, keep track of their locations. Sometimes threading a bolt back in a part, or putting the washers and nut back on a stud, can prevent mix-ups later. If nuts and bolts cannot be’ returned to their original locations, they should be kept in a compartmented box or a series of small boxes. A cupcake or muffin tin is ideal for this purpose, since each cavity can hold the bolts and nuts from a particular area (i.e. oil pan bolts, valve cover bolts, engine mount bolts, etc.). A pan of this type is especially helpful when working on assemblies with very small parts, such as the carburetor,

alternator, valve train or interior dash and trim pieces. The cavities can be marked with paint or tape to identify the contents. Whenever wiring looms, harnesses or

connectors are separated, it is a good idea to identify the two halves with numbered pieces of masking tape so they can be easily reconnected.

Gasket sealing surfaces

Hose removal tips

Throughout any vehicle, gaskets are used to seal the mating surfaces between two parts and keep lubricants, fluids, vacuum or pressure contained in an assembly.

Warning: /f the vehicle is equipped with air conditioning, do not disconnect any of the A/C hoses without first having the system depressurized by a dealer service department or a service station.

Many times these gaskets are coated with a liquid or paste-type gasket sealing compound before assembly. Age, heat and pressure can sometimes cause the two parts to stick together so tightly that they are very difficult to separate. Often, the assembly can be loosened by striking it with a soft-face hammer near the mating surfaces. A regular hammer can be used if a block of wood is placed between the hammer and the part. Do not hammer on cast parts or parts that could be easily damaged. With any particularly stubborn part, always recheck to make sure that every fastener has been removed. Avoid using a screwdriver or bar to pry apart an assembly, as they can easily mar the gasket sealing surfaces of the parts, which must remain smooth. If prying is absolutely necessary, use an old broom handle, but keep in mind that extra clean up will be necessary if the wood splinters. After the parts are separated, the old gasket must be carefully scraped off and the gasket surfaces cleaned. Stubborn gasket material can be soaked with rust penetrant or treated with a special chemical to soften it so it can be easily scraped off. A scraper can be fashioned from a piece of copper tubing by flattening and sharpening one end. Copper is recommended because it is usually softer than the surfaces to be scraped, which reduces the chance of gouging the part.

Some gaskets can be removed with a wire brush, but regardless of the method used, the mating surfaces must be left clean and smooth. If for some reason the gasket surface is gouged, then a gasket sealer thick enough to fill scratches will have to be used

during reassembly of the components. For most applications, a non-drying (or semi-drying) gasket sealer should be used.

Hose removal precautions closely parallel gasket removal precautions. Avoid scratching or gouging the surface that the hose mates against or the connection may leak. This is especially true for radiator hoses. Because of various chemical reactions, the rubber in hoses can bond itself to the metal spigot that the hose fits over. To remove a hose, first loosen the hose clamps that secure it to the spigot. Then, with slip-joint pliers, grab the hose at the clamp and rotate it around the spigot. Work it back and forth until it is completely free, then pull it off. Silicone or other lubricants will ease removal if ~

they can be applied between the hose and

~

the outside of the spigot. Apply the same lubricant to the inside ofthe hose and the outside of the spigot to simplify installation. As a last resort (and if the hose is to be replaced with a new one anyway), the rubber can be slit with a knife and the hose peeled from the spigot. If this must be done, be careful that the metal connection is not damaged.

If a hose clamp is broken or damaged, do not reuse it. Wire-type clamps usually weaken with age, so it is a good idea to replace them with screw-type clamps whenever a hose is removed.

Tools A selection

of good tools is a basic

requirement for anyone who plans to maintain and repair his or her own vehicle. For the owner who has few tools, the initial invest-

ment might seem high, but when compared to the spiraling costs of professional auto maintenance and repair, it is a wise one.

To help the owner decide which tools are needed to perform the tasks detailed in this manual, the following tool lists are

Eventually the basic kit will be expanded into the repair and overhaul tool set. Over a period of time, the experienced do-it-yourselfer will assemble a tool set complete enough for most repair and overhaul procedures and will add tools from the special category when it is

The tools in this list include those which are not used regularly, are expensive to buy, or which need to be used in accordance with their manufacturer’s instructions. Unless these tools will be used frequently, it is not very economical to purchase many of them. A consideration would be to split the cost and use between yourself and a friend or friends. In addition, most of these tools can be obtained from a tool rental shop on a temporary basis. This list primarily contains only those tools and instruments widely available to the public, and not those special tools produced by the vehicle manufacturer for distribution to dealer service departments. Occasionally, references to the manufacturer’s special tools are included in the text of this manual. Generally, an alternative method of doing the job without the special tool is offered. How-

ever, sometimes there is no alternative to their use. Where this is the case, and the tool cannot be purchased or borrowed, the work should be turned over to the dealer service department or an automotive repair shop.

Maintenance techniques, tools and working facilities Buying tools For the do-it-yourselfer who is just starting to get involved in vehicle maintenance and repair, there are a number of options available when purchasing tools. If maintenance and minor repair is the extent of the work to be done, the purchase of individual

tools is satisfactory. If, on the other hand,

extensive work is planned, it would be a good idea to purchase a modest tool set from:one of the large retail chain stores. A set can usually be bought at a substantial savings over the individual tool prices, and they often come with a tool box. As additional tools are needed, add-on sets, individual tools and a larger tool box can be purchased to expand the tool selection. Building a tool set gradually allows the cost of the tools to be spread over a longer period of time and gives the mechanic the freedom to choose only those tools that will actually be used. Tool stores will often be the only source of some of the special tools that are needed, but regardless of where tools are bought, try to avoid cheap ones, especially when buying screwdrivers and sockets, because they won't last very long. The expense involved in replacing cheap tools will eventually be greater than the initial cost of quality tools.

Care and maintenance of tools Good tools are expensive, so it makes sense to treat them with respect. Keep them

clean and in usable condition and store them properly when not in use. Always wipe off any dirt, grease or metal chips before putting them away. Never leave tools lying around in the work area. Upon completion of a job, always check closely under the hood for tools that may have been left there so they won’t get lost during a test drive. Some tools, such as screwdrivers, pliers, wrenches and sockets, can be hung ona panel mounted on the garage or workshop wall, while others should be kept in a tool box or tray. Measuring instruments, gauges, meters, etc. must be carefully stored where they cannot be damaged by weather or impact from other tools. When tools are used with care and

stored properly, they will last a very long time. Even with the best of care, though, tools will wear out if used frequently. When a tool is damaged or worn out, replace it. Subsequent jobs will be safer and more enjoyable if you do.

How to repair damaged threads Sometimes, the internal threads of a nut

or bolt hole can become stripped, usually from overtightening. Stripping threads is an all-too-common occurrence, especially when ‘working with aluminum parts, because aluminum is so soft that it easily strips out. Usually, external or internal threads are only partially stripped. After they’ve been cleaned up with a tap or die, they’ll still work.

Sometimes, however, threads are badly damaged. When this happens, you’ve got three choices: 1) Drill and tap the hole to the next suitable oversize and install a larger diameter

bolt, screw or stud.

:

2) Drill and tap the hole to accept a threaded plug, then drill and tap the plug

to the original screw size. You can also buy a plug already threaded to the original size. Then you simply drill a hole to the specified size, then run the threaded plug into the hole with a bolt and jam nut. Once the plug is fully seated, remove the jam nut and bolt. 3) The third method uses a patented thread repair kit like Heli-Coil or Slimsert. These easy-to-use kits are designed to repair damaged threads in‘ straightthrough holes and blind holes. Both are available as kits which can handle a variety of sizes and thread patterns. Drill the hole, then tap it with the special included tap. Install the Heli-Coil and the hole is back to its original diameter and thread pitch. : Regardless of which method you use, be sure to proceed calmly and carefully. A little impatience or carelessness during one of these relatively simple procedures can ruin your whole day’s work and cost you a bundle if you wreck an expensive part.

Working facilities Not to be overlooked when discussing tools is the workshop. If anything more than routine maintenance is to be carried out, some sort of suitable work area is essential. It is understood, and appreciated, that many home mechanics do not have a good workshop or garage available, and end up removing an engine or doing major repairs outside. It is recommended, however, that the overhaul or repair be completed under the cover of a roof. A clean, flat workbench or table of comfortable working height is an absolute necessity. The workbench should be equipped with a vise that has a jaw opening of at least four inches. As mentioned previously, some clean, dry storage space is also required for tools, as well as the lubricants, fluids, cleaning solvents, etc. which soon become necessary.

Sometimes waste oil and fluids, drained from the engine or cooling system during normal maintenance or repairs, present a disposal problem. To avoid pouring them on the ground or into a sewage system, pour the used fluids into large containers, seal them with caps and take them to an authorized disposal site or recycling center. Plastic jugs, such as old antifreeze containers, are ideal for this purpose. Always keep a supply of old newspapers and clean rags available. Old towels are excellent for mopping up spills. Many mechanics use rolls of paper towels for most work because they are readily available and disposable. To help keep the area under the vehicle clean, a large cardboard box can be cut open and flattened to protect the garage or shop floor. Whenever working over a painted surface, such as when leaning over a fender to service something under the hood, always cover it with an old blanket or bedspread to protect the finish. Vinyl covered pads, made especially for this purpose, are available at auto parts stores.

Booster battery (jump) starting Observe the following precautions when using a booster battery to start a vehicle:

Dead battery

Booster battery

a) Before connecting the booster battery, make sure the ignition switch is in the Off position. b) Turn off the lights, heater and other electrical loads. c) Your eyes should be shielded. Safety goggles are a good idea. d) Make sure the booster battery is the same voltage as the dead one in the vehicle. e) The two vehicles MUST NOT TOUCH each other. f) Make sure the transmission is in Neutral (manual transaxle) or Park (automatic transaxle). g) If the booster battery is not a maintenance-free type, remove the vent caps and lay a cloth over the vent holes. Connect the red jumper cable to the positive (+) terminals of each

battery. Connect one end of the black cable to the negative (-) terminal of the booster battery. The other end of this cable should be connected to a good ground on the engine block (see illustration). Make sure the cable will not come into contact with the fan, drivebelts or other moving parts of the engine. Start the engine using the booster battery, then, with the engine running at idle speed, disconnect the jumper cables in the reverse order of connection.

Make the booster battery cable connections in the numerical order shown (note that the negative cable of the booster battery is NOT attached to the negative terminal of the dead battery)

Anti-theft audio system General information 1 Some of these models are equipped with THEFTLOCK audio systems, which include an anti-theft feature that will render the stereo

inoperative if stolen. If the power source to the stereo is cut with the anti-theft feature activated, the stereo will be inoperative. Even if the power source is immediately re-connected, the stereo will not function. 2 _ If your vehicle is equipped with this anti-theft system, do not disconnect the battery, remove the stereo or disconnect related components unless you have either turned off the feature or have the individual ID (code) number for the stereo.

Disabling the anti-theft feature 3 Press the stereo’s 1 and 4 buttons at the same time for five seconds with the ignition on and the radio power off. The display will show SEC, indicating the unit is in the secure mode (anti-theft feature enabled). 4 Press the MIN button. The display will show “O00”. 5 Press the MIN button until the last two numbers are the same as your secret code. 6 Press HR until the first one or two numbers displayed match your code. The numbers will be displayed as entered. 7 Press AM/FM. If the display shows “__ _” you have successfully

disabled the anti-theft feature. If SEC is displayed, the code you entered was incorrect and the anti-theft feature is still enabled.

Unlocking the stereo after a power loss 8

When the power is restored to the stereo, the stereo won’t turn on

and LOC will appear on the display. Enter your ID code as follows,

_ without pausing more than 15 seconds between Steps. 9 Turn the ignition switch to ON, but leave the stereo off. 10 Press the MIN button. “O00” should display. 11. Press the HR button to make the last two numbers match your code, then release the button. 12 Press the HR button until the first one or two numbers match your code. 13. Press AM/FM. SEC should appear, indicating the stereo is unlocked. If LOC appears, the numbers you entered were not correct and the stereo is still inoperative. ‘ 14 You should have the code written down in a secure place, for use in unlocking the THEFTLOCK feature. Note: When performing the above procedures, you are allowed only eight tries. After that, the system shuts down for an hour, with the radio displaying “INOP.” At the end of that period, you have another three tries, after which you will have to bring the vehicle to your dealer for activation.

| Jacking and towing Jacking The

jack

supplied

with

the

vehicle

should only be used for raising the vehicle when changing a tire or placing jackstands under the frame. Warning: Never work under the vehicle or start the engine while the jack is being used as the only means of support. The vehicle should be on level ground with the hazard flashers on, the wheels blocked, the parking brake applied and the transmission in Park (automatic) or Reverse (manual). If a tire is being changed, loosen the lug nuts one-half turn and leave them in place until the wheel is raised off the ground. Make sure no one is in the vehicle as it’s being raised with the jack. Place the jack under the vehicle suspension in the indicated position (see illustra-

Front jack location

tions). Operate the jack with a slow, smooth motion until the wheel is raised off the

ground. Remove the lug nuts; pull off the wheel, install the spare and thread the lug nuts back on with the beveled sides facing in. Tighten them snugly, but wait until the vehicle is lowered to tighten them completely. Lower the vehicle, remove the jack and tighten the nuts (if loosened or removed) in a criss-cross pattern. If possible, tighten them with a torque wrench (see Chapter 1 for the torque figures). If you don’t have access to a torque wrench, have the nuts checked by a service station or repair shop as soon as possible.

Towing These vehicles can be towed

with all

four wheels on the ground, provided speeds don’t exceed 35 mph and the distance is less than 50 miles. Equipment specifically designed for towing should be used and must be attached to the main structural members of the vehicle, not the bumper or brackets. Safety is a major consideration when towing and all applicable state and local laws must be obeyed. A safety chain must be used at all times While towing, the parking brake should be released and the transmission and transfer case (if equipped) must be in Neutral. The steering must be unlocked (ignition switch in the Off position). Remember that power

steering and power brakes will not work with the engine off.

Automotive chemicals and lubricants A number of automotive chemicals and lubricants are available for use during vehicle maintenance and repair. They include a wide variety of products ranging from cleaning solvents and degreasers to lubricants and protective sprays for rubber, plastic and vinyl.

in disc brake equipped vehicles. It usually contains molybdenum disulfide (moly), which is a dry-type lubricant. White grease is a heavy grease for metal-to-metal applications where water is a problem. White grease stays soft under both low and high temperatures (usually from -100

Cleaners

to +190-degrees F), and will not wash off or

Carburetor cleaner and choke cleaner is a strong solvent for gum, varnish and car-

dilute in the presence of water. Assembly lube is a special extreme

bon. Most carburetor cleaners leave a drytype lubricant film which will not harden or gum up. Because of this film it is not recommended for use on electrical components. Brake system cleaner is used to remove grease and brake fluid from the brake system, where clean surfaces are absolutely necessary. It leaves no residue and often eliminates brake squeal caused by contaminants. Electrical cleaner removes oxidation, corrosion and carbon deposits from electrical contacts, restoring full current flow. It can also be used to clean spark plugs, carburetor jets, voltage regulators and other parts where an oil-free surface is desired. Demoisturants remove water and moisture from electrical components such as alternators, voltage regulators, electrical connectors and fuse blocks. They are non-conductive, non-corrosive and non-flammable. Degreasers are heavy-duty solvents used to remove grease from the outside of the engine and from chassis components. They can be sprayed or brushed on and, depending on the type, are rinsed off either with water or solvent.

pressure lubricant, usually containing moly, used to lubricate high-load parts (such as

Lubricants Motor oil is the lubricant formulated for use in engines. It normally contains a wide variety of additives to prevent corrosion and reduce foaming and wear. Motor oil comes in various weights (viscosity ratings) from 0 to 50. The recommended weight of the oil depends on the season, temperature and the demands on the engine. Light oil is used in cold climates and under light load conditions. Heavy oil is used in hot climates and where high loads are encountered. Multi-viscosity oils are designed to have characteristics of both light and heavy oils and are available in a number of weights from 5W-20 to 20W-50. Gear oil is designed to be used in differentials, manual transmissions and other areas where high-temperature lubrication is required. Chassis and wheel bearing grease is a heavy grease used where increased loads and friction are encountered, such as for wheel bearings, balljoints, tie-rod ends and universal joints. High-temperature wheel bearing grease is designed to withstand the extreme temperatures encountered by wheel bearings

main and rod bearings and cam lobes) for initial start-up of a new engine. The assembly lube lubricates the parts without being squeezed out or washed away until the ‘ engine oiling system begins to function. Silicone lubricants are used to protect rubber, plastic, vinyl and nylon parts. Graphite lubricants are used where oils cannot be used due to contamination problems, such as in locks. The dry graphite will lubricate metal parts while remaining uncontaminated by dirt, water, oil or acids. It is electrically conductive and will not foul electrical contacts in locks such as the ignition switch. Moly penetrants |oosen and lubricate frozen, rusted and corroded fasteners and prevent future rusting or freezing. Heat-sink grease is a special electrically non-conductive grease that is used for mounting electronic ignition modules where it is essential that heat is transferred away from the module.

Sealants RTV sealant is one of the most widely used gasket compounds. Made from silicone, RTV is air curing, it seals, bonds, waterproofs, fills surface irregularities,

remains flexible, doesn’t shrink, is relatively easy to remove, and is used as a supplementary sealer with almost all low and medium

temperature gaskets. Anaerobic sealant is much like RTV in that it can be used either to seal gaskets or to form gaskets by itself. It remains flexible, is solvent resistant and fills surface imperfec-.

tions. The difference between an anaerobic sealant and an RTV-type sealant is in the curing. RTV curés when exposed to air, while an anaerobic sealant cures only in the absence of air. This means that an anaerobic sealant cures only after the assembly of parts, seal-

ing them together. Thread and pipe sealant is used for sealing hydraulic and pneumatic fittings and vacuum lines. It is usually made from a Teflon compound, and comes in a spray, a paint-on liquid and as a wrap-around tape.

Chemicals Anti-seize compound prevents seizing,

galling, cold welding, rust and corrosion in

fasteners. High-temperature anti-seize, usually made with copper and graphite lubricants, is used for exhaust system and exhaust manifold bolts. Anaerobic locking compounds are used to keep fasteners from vibrating or working loose and cure only after installation, in the absence of air. Medium strength locking compound is used for small nuts, bolts and screws that may be removed later. Highstrength locking compound is for large nuts, bolts and studs which aren’t removed on a regular basis.

Oil additives range from viscosity index improvers to chemical treatments that claim to reduce internal engine friction. It should be noted that most oil manufacturers caution against using additives with their oils. Gas additives perform several functions, depending on their chemical makeup. They usually contain solvents that help dissolve gum and varnish that build up on carburetor, fuel injection and intake parts. They also serve to break down carbon deposits that form on the inside surfaces of the combustion chambers. Some additives contain upper cylinder lubricants for valves and piston rings, and others contain chemicals to remove condensation from the gas tank.

Miscellaneous Brake fluid is specially formulated hydraulic fluid that can withstand the heat and pressure encountered in brake systems. Care must be taken so this fluid does not come in contact with painted surfaces or plastics. An opened container should always be resealed to prevent contamination by water or dirt. Weatherstrip adhesive is used to bond weatherstripping around doors, windows and trunk lids. It is sometimes used to attach trim pieces.

Undercoating is a petroleum-based, tar-like substance that is designed to protect metal surfaces on the underside of the vehicle from corrosion. It also acts as a sounddeadening agent by insulating the bottom of the vehicle. Waxes and polishes are used to help protect painted and plated surfaces from the weather. Different types of paint may require the use of different types of wax and polish. Some polishes utilize a chemical or abrasive cleaner to help remove the top layer of oxidized (dull) paint on older vehicles. In recent Years many non-wax polishes that contain a wide variety of chemicals such as polymers and silicones have been introduced. These non-wax polishes are usually easier to apply and last longer than conventional waxes and polishes.

Safety fi rst! Regardless of how enthusiastic you may be about getting on with the job at hand, take the time to ensure that your safety is not jeopardized. A moment’s lack of attention can result in an accident, as can failure to observe certain simple safety precautions. The possibility of an accident will always exist, and the following points should not be considered a comprehensive list of all dangers. Rather, they are intended to make you aware of the risks and to encourage’ a’safety conscious approach to all work you carry out on your vehicle.

Essential DOs and DON’Ts DON’T rely on a jack when working under the vehicle. Always use approved jackstands to support the weight of the vehicle and place them under, the recommended lift or support points. : DON’T attempt to loosen extremely tight fasteners (i.e. wheel lug nuts) while the vehicle is on a jack - it may fall. DON’T start the engine without first making sure that the transmission is in Neutral (or Park where applicable) and the parking brake

is set. DON’T remove the radiator cap from a hot cooling system - let it cool or cover it with a cloth and release the pressure gradually. DON’T attempt to drain the engine oil until you are sure it has cooled to the point that it will not burn you. DON’T touch any part of the engine or exhaust system until it has cooled sufficiently to avoid burns. DON’T siphon toxic liquids such as gasoline, antifreeze and brake fluid by mouth, or allow them to remain on your skin. DON’T inhale brake lining dust - it is potentially hazardous (see Asbestos below). DON’T allow spilled oil or grease to remain on the floor - wipe it up before someone slips on it. DON’T use loose fitting wrenches or other tools which may slip and cause injury. DON’T push on wrenches when loosening or tightening nuts or bolts. Always try to pull the wrench toward you. If the situation calls for pushing the wrench away, push with an open

etc. and when working under a vehicle. DO keep loose clothing and long hair well out of the way of moving parts. DO make sure that any hoist used has a safe working load rating adequate for the job. DO get someone to check on you periodically when working alone on a vehicle. DO carry out work in a logical sequence and make sure that everything is correctly assembled and tightened. DO keep chemicals and fluids tightly capped and out of the reach of children and pets. DO remember that your vehicle’s safety affects that of yourself and others. If in doubt on any point, get professional advice.

carefully. Never use materials from unmarked containers. Never run the engine in an enclosed space, such as a garage. Exhaust fumes contain carbon monoxide, which is extremely poisonous. If you need to run the engine, always do so in the open air, or at least have the rear of the vehicle outside the work area. If you are fortunate enough to have the use of an inspection pit, never drain or pour gasoline and never run the engine while the vehicle is over the pit. The fumes, being heavier than air, will concentrate in the pit with possibly lethal results.

Asbestos

Never create a spark or allow a bare light bulb near a battery. They normally give off a certain amount of hydrogen gas, which is highly explosive. Always disconnect the battery ground (-) cable at the battery before working on the fuel or electrical systems. If possible, loosen the filler caps or cover when charging the battery from an external source (this does not apply to sealed or maintenance-free batteries). Do not charge at an excessive rate or the battery may burst. Take care when adding water to a non maintenance-free battery and when carrying a battery. The electrolyte, even when diluted, is very corrosive and should not be allowed to contact clothing or skin. Always wear eye protection when cleaning the battery to prevent the caustic deposits from entering your eyes.

Certain friction, insulating, sealing, and

other products - such as brake linings, brake bands, clutch linings, torque converters, gaskets, etc. - may contain asbestos. Extreme care must be taken to avoid inhalation of dust from such products, since it is hazardous to health. If in doubt, assume that they do contain asbestos.

Fire Remember at all times that gasoline is highly. flammable. Never smoke or have any kind of open flame around when working on a vehicle. But the risk does not end there. A spark caused by an electrical short circuit, by two metal surfaces contacting each other, or even by static electricity built up in your body under certain conditions, can ignite gasoline vapors, which in a confined space are highly explosive. Do not, under any circumstances, use gasoline for cleaning parts. Use an approved safety solvent. Always disconnect the battery ground (-) cable at the battery before working on any part of the fuel system or electrical system. Never risk spilling fuel on a hot engine or exhaust component. It is strongly recommended that a fire extinguisher suitable for

use on fuel and electrical fires be kept handy in the garage or workshop at all times. Never

try to extinguish a fuel or electrical fire with

The battery

Household current When using an electric power tool, inspection light, etc., which operates on household current, always make sure that the tool is correctly connected to its plug and that, where necessary, it is properly grounded. Do not use such items in damp conditions and, again, do not create a spark or apply excessive heat in the vicinity of fuel or fuel vapor.

should slip. ; DON’T attempt to lift a heavy component alone - get someone to help you. DON’T rush or take unsafe shortcuts to finish a job. DON’T allow children or animals in-or around the vehicle while you are working on it. DO wear eye protection when using power tools such as a drill, sander, bench grinder,

Certain fumes are highly toxic and can quickly cause unconsciousness and even death if inhaled to any extent. Gasoline vapor falls into this category, as do the vapors from some cleaning solvents. Any draining or pouring of such volatile fluids should be done in a well ventilated area. When using cleaning fluids and sol-

0-22 This section is an easy reference guide to the more common problems which may occur during the operation of your vehicle. The problems and their possible causes are grouped under headings denoting various components or systems, such as Engine, Cooling system, etc. They also refer you to the chapter and/or section which deals with the problem. Remember, successful troubleshooting ’ isn’t a mysterious “black art” practiced only ~ by professional mechanics. It’s simply the result of the right knowledge combined with an intelligent, systematic approach to a problem. Always follow a logical approach, starting with the simplest solution and working

through to the most complex - and never overlook the obvious. Anyone can run the gas tank dry or leave the lights on overnight, so don’t assume that it can’t happen to you. Finally, always try to establish a clear idea why a problem has occurred and take steps to ensure it doesn’t happen again. For

example, if the electrical system fails because of a poor connection, check all other connections in the system to make sure they don’t fail as well. If a particular fuse continues to blow, find out why - don’t just replace one fuse after another. Remember, failure of a small component often indicates potential failure or malfunction of a more important component or system.

Troubleshooting 2

1 Fuel tank empty. 2 Battery discharged (engine rotates slowly). Check the operation of electrical components as described in previous Section. ay 3 Battery terminal connections loose or corroded. See previous Section.

4 Fuel not reaching the fuel injection unit. Check for clogged fuel filter or lines and defective fuel pump. Also make sure the tank vent lines aren’t clogged (Chapter 4).

5 Faulty distributor components. Check the cap and rotor (Chapter 1). 6 Defective oil pressure/fuel pump switch (Chapters 2B and 4). 7 Low cylinder compression. Check as described in Chapter 2. 8 Valve clearances not properly adjusted (Chapter 2A). 9 Water in fuel. Drain tank and fill with new fuel. 10 Defective ignition coil (Chapter 5). 11. Dirty or clogged fuel injector (Chapter 4). 12 Wet or damaged ignition components (Chapters 1 and 5). 13 Worn, faulty or incorrectly gapped spark plugs (Chapter 1). 14 Broken, loose or disconnected wires in the starting circuit (see previous Section).

area. Replace the bearing and/or service or replace the crankshaft (Chapter 2). 2 A similar (yet slightly higher pitched) noise to the crankshaft knocking described in the previous paragraph, that becomes more rapid as the engine accelerates, indicates worn or damaged connecting rod bearings (Chapter 2). The procedure for locating the problem cylinder is the same as described in Paragraph 1. 3 An overlapping metallic noise that increases in intensity as the engine speed increases, yet diminishes as the engine warms up indicates abnormal piston and cylinder wear (Chapter 2).To locate the problem cylinder, use the procedure described in Paragraph 1. 4 A rapid clicking noise that becomes faster as the engine accelerates indicates a worn piston pin or piston pin hole. This sound will happen each time the piston hits the highest and lowest points in the stroke (Chapter 2). The procedure for locating the problem piston is described in Paragraph 1. 5 A metallic clicking noise coming from the water pump indicates worn or damaged water pump bearings or pump. Replace the water pump with a new one (Chapter 3). 6 A rapid tapping sound or clicking sound that becomes faster as the engine speed increases indicates “valve tapping” or improperly adjusted valve clearances. This can

be identified by holding one end of a section of hose to your ear and placing the other end at different spots along the rocker arm cover. The point where the sound is loudest indicates the problem valve. Adjust the valve clearances (Chapter 2A). If the problem persists, you likely have a collapsed valve lifter or other damaged valve train component. Changing the engine

oil and adding a high viscosity oil treatment will sometimes cure a stuck lifter problem. If the problem still persists, the lifters, pushrods and rocker arms must be removed for inspection (see Chapter 2). 7 A steady metallic rattling or rapping sound coming from the area of the timing chain cover indicates a worn, damaged or out-of-adjustment timing chain. Service or replace the chain and related components

(Chapter 2).

External coolant leakage

1 Deteriorated or damaged hoses. Loose clamps at hose connections (Chapter 1). 2 Water pump seals defective. If this is the case, water will drip from the weep hole in the water pump body (Chapter 3). 3 Leakage from radiator core or header tank. This will require the radiator to be professionally repaired (see Chapter 3 for removal procedures). 4 Engine drain plugs or water jacket freeze plugs leaking (see Chapters 1 and 2). 5 Leak from coolant temperature switch (Chapter 3). 6 Leak from damaged gaskets or small cracks (Chapter 2). 7 Damaged head gasket. This can be verified by checking the condition of the engine oil as noted in Section 30.

Degreasing agents and/or steam cleaning will achieve this. With the underside clean, drive the vehicle at low speeds so the air flow will not blow the leak far from its source. Raise the vehicle and determine where the leak is located.

Chapter 7 deals with adjusting the TV linkage to enable the four-speed transmission to downshift properly.

Pronounced wear in the universal joint bearings. Replace U-joints or driveshafts, as

necessary.

Engine will start in gears other than Park or Neutral

Automatic transmission Note: Due to the complexity of the automatic transmission,

it’s

difficult

for

the

home

mechanic to properly diagnose and service. For problems other than the following, the vehicle should be taken to a reputable mechanic.

47

Fluid leakage

1

Automatic transmission fluid is a deep

red color, and fluid leaks should not be confused with engine oil which can easily be

blown by air flow to the transmission. 2 To pinpoint a leak, first remove all builtup dirt and grime from the transmission. Degreasing agents and/or steam cleaning will achieve this. With the underside clean, drive the vehicle at low speeds so the air flow will not blow the leak far from its source. Raise the vehicle and determine where the leak is located. Common areas of leakage are:

Chapter 7 deals with adjusting the Neutral start switch installed on automatic transmissions.

51

Transmission slips, shifts rough, is noisy or has no drive in Forward or Reverse gears

1

There are many probable causes for the

above problems, but the home mechanic should concern himself only with one possi-

bility; fluid level. 2 Before taking the vehicle to a shop, check the .fluid level and condition as described in Chapter 1. Add fluid, if necessary, or change the fluid and filter if needed. If problems persist, have a professional diagnose the transmission.

a) Fluid pan: tighten mounting bolts and/or replace pan gasket as necessary (Chapter 1).

b) Rear extension: tighten bolts and/or replace oil sea] as necessary. c) Filler pipe: replace the rubber oil seal where pipe enters transmission case. d) Transmission oil lines: tighten fittings where lines enter transmission case and/or replace lines. e) Vent pipe: transmission overfilled and/or water in fluid (see checking procedures, Chapter 1).

f) Speedometer connector: replace the O-ring where speedometer cable enters transmission case.

Driveshaft Note: Refer to Chapter 8, unless otherwise specified, for service information.

52

Metallic grating sound consistent with vehicle speed

Vibration

Note: Before blaming the driveshaft, make sure the tires are perfectly balanced and perform the following test. 1 Install a tachometer inside the vehicle to monitor engine speed as the vehicle is driven. Drive the vehicle and note the engine speed at which the vibration (roughness) is most pronounced. Now shift the transmission to a different gear and bring the engine speed to the same point. 2 If the vibration occurs at the same engine speed (rpm) regardless of which gear the transmission is in, the driveshaft is NOT at fault since the driveshaft speed varies. 3 If the vibration decreases or is eliminated when the transmission is in a different gear at the same engine speed, refer to the following probable causes. 4 Bent or dented driveshaft. Inspect and

replace as necessary.

5

_Undercoating or built-up dirt, etc. on the

driveshaft. Clean the shaft thoroughly. 6 Worn universal joint bearings. Replace the U-joints or driveshaft as necessary. 7 _ Driveshaft and/or companion flange out of balance. Check for missing weights on the shaft. Remove driveshaft and reinstall 180degrees from original position, then recheck. Have the driveshaft balanced if problem persists. 8 Loose driveshaft mounting bolts/nuts. 9 Defective center bearing, if so equipped. 10 Worn transmission rear bushing (Chapter 7).

Leaks at front of driveshaft

Defective transmission rear seal. See Chapter 7 for replacement procedure. As this is done, check the splined yoke for burrs or roughness that could damage the new seal. Remove burrs with a fine file or whetstone.

56

Scraping noise

Make sure the dust cover on the sleeve yoke isn’t rubbing on the transmission extension housing.

~Common

spark plug conditions -NORMAL Symptoms: Brown to grayish-tan color and slight electrode wear. Correct heat range for engine and operating conditions. Recommendation: When new spark plugs are installed, replace with plugs of the same heat range.

a TOO HOT

WORN

Symptoms: Blistered, white insulator, eroded electrode and absence of deposits. Results in shortened plug life. Recommendation: Check for the correct plug heat range, overadvanced ignition timing, lean fuel mixture, intake manifold vacuum leaks, sticking valves and insuffi-

Symptoms: Rounded electrodes with a small amount of deposits on the firing end. Normal color. Causes hard starting in damp or cold weather and poor fuel economy. Recommendation: Plugs have been left in the engine too long. Replace with new plugs of the same heat range. Follow the recommended maintenance schedule.

cient engine cooling. ”

CARBON

PREIGNITION

DEPOSITS

Symptoms: Dry sooty deposits indicate a rich mixture or weak ignition. Causes misfiring, hard starting and hesitation. Recommendation: Make sure the

plug has the correct heat range.

Check for a clogged air filter or problem in the fuel system or engine management system. Also check for ignition system problems.

ASH DEPOSITS Symptoms:

Light brown

deposits

encrusted on the side or center electrodes or both. Derived from oil and/or fuel additives. Excessive amounts may mask the spark, causing misfiring and hesitation during acceleration. Recommendation: _ If excessive deposits accumulate over a short time or low mileage, install new valve guide seals to prevent seepage of oil into the combustion chambers. Also try changing gasoline brands.

Symptoms: Melted electrodes. Insulators are white, but may be dirty due to misfiring or flying debris in the combustion chamber. Can lead to engine damage. Recommendation: Check for the correct plug heat range, over-

advanced ignition timing, lean fuel mixture, insufficient engine cooling and lack of lubrication.

HIGH SPEED GLAZING Symptoms: |nsulator has yellowish, glazed appearance. Indicates that combustion chamber temper-

atures have risen suddenly during hard acceleration. Normal deposits melt to form a conductive coating. Causes misfiring at high speeds. Recommendation: Install new plugs. Consider using a colder plug if driving habits warrant. ‘

DETONATION Symptoms:

OIL DEPOSITS Symptoms: Oily coating caused by poor oil control. Oil is leaking past worn valve guides or piston rings into the combustion chamber. Causes hard starting, misfiring and hesitation. Recommendation: Correct the mechanical condition with necessary repairs and install new plugs.

Insulators

may

be

cracked or chipped. Improper gap setting techniques can also result in a fractured insulator tip. Can lead to piston damage. Recommendation: Make sure the fuel anti-knock values meet engine requirements.

Use care when

set-

ting the gaps on new plugs. Avoid lugging the engine.

MECHANICAL DAMAGE Symptoms:

GAP BRIDGING Symptoms:

Combustion

deposits

lodge between the electrodes. Heavy deposits accumulate and bridge the electrode gap. The plug ceases to fire, resulting in a dead cylinder. Recommendation: Locate the faulty plug and remove the deposits from between the electrodes.

May be caused

by a

foreign object in the combustion chamber or the piston striking an incorrect reach (too long) plug. Causes a dead cylinder and could result in piston damage. Recommendation: Repair the mechanical damage. Remove the foreign object from the engine and/or install the correct reach plug.
